As you know we offer our services free of charge, and it will stay that way. Though, we do not really make money with the project and all costs (servers, domains, time) are paid by ourselves. If you want to donate a few euro's or dollars to the project to help us keeping it alive you can do so by using PayPal:

We would really appreciate a small donation!
